TRUCK.

Original application filed February 14, 1921, Serial No. 444,868.Divided-and this application-filed March 17, 1924. Serial No. 699,766.

This invention relates to improvements in trucks, and particularly inload carrying boxes mounted on the trucks.

It is an object of the invention to provide ina load carrying box meansfor selectively permitting the introduction of assorted materials intodifferent portions of the box and for-mixing the materials thusintroduced therein. For this: purpose the load carrying box is dividedinto a plurality of compartments adapted to individually receive thevarious materials and which communicate with a collective space; fromthis collective space the mixture may thenbe transferred to a conveyingdevice or the like, to carry the mixture to a concrete mixing machine orsimilar place forluse. 1

It is another object of the invention to provide aload carrying box witha plurality of compartments, the volume of the individual compartmentsbeingselectively adjustable to I facilitate the proportioning of themixture of those materials whiclrare to be carried to the collectivecompartment;

Another object of the invention istoprovide in combination with a loadcarryingbox a mechanism which can be controlled from a remote positionby an attendant for opening a gate of thecollective receptacle, intowhich the various classes of material have been thrown this gate ofthecollective receptacle being closable in some other suitable way.

With these and other objects in view, an

embodiment of the invention is illustrated in the accompanying drawingsand is described inthe following'specification.

Fig. 1 is a side elevation'of the machine showing a scoop in full linesinacharging position and in dottedlines in a position to discharge intothe load carrying box.

Fig. 2 isa top plan view partly inse'ction of the. load carryingbox,shown in combination with a scoop in charging position.

3 isa rear elevation ofthe load carryingfbox showing how it is supportedon a vehicle frame.

Fig. 4 is a fragmental vertical sectional View taken through the rearpart ofthe box and through the charging scoop. I Fig. 5 is a perspectivesectional view show ingthe interior of the box.

Fig. 6 is a top planview of the sameshown partly in section.

Fig. 7 shows a detail sectional view of the means provided for adjustingthe partition walls with. respect to the sides of the box.

Fig. 8 is another sectional detail view showv ing the means foradjusting the companion sections of the partition walls.

The load conveying box 18 is shown in Fig. l as being mounted on a truckwhich comprises a frame 1, a single front wheel 2 by which the truckmaybe steered, andrear wheels lwhich may be driven in some suitable way byan engine, the hood of which is indicated at 5. The operators seat 6v ismounted here relatively to the engine hood 5 and to the steering post 7in a manner ,opposite from the ordinary arrangement of an operators seatin'power driven vehicles, as it is the intention to control fromtheoperators position-6 not only the'travel of the truck but alsotheoperations of charging the load carrying box 18' which is mountedthereon. r

Tosupport the load carrying box 18 on the frame 1 of the truck, thelatter is equipped with a supportingbracket structure indicatedgenerally at 17, Fig. 4;. The box is -pro vided with a vertical rearwall 21 and a slanting bottom 22. The front wall of this box, asindicated at 19, is preferably curved and a number of adjustablediaphragms or partition walls are located between the side walls 23 ofthe box, as perspectively shown in Fig. 5.

For the support of these diaphragms or partition walls which divide theinterior of the box into a plurality of selectively adjustablecompartments, angle irons 24; are rigidly secured to the side walls 23.in slanting position; These angle irons fixedly support inclinedupperplates 25,- to the lower edges of which plates or wings 26 and 27are pivotallyv secured. These hinged plates may be: curved, as the plate26 is shown, or straight, asthe plate 27 is'shown, and extenddownward-into the interior of the carrying. box 18. These platesfurthermoreare provided withlugs 28 near their lateraledges, Fig. 7, inthe form of short lengths of angle. irons or the like through whichbolts 29 extend. I

e For thepurpose of rendering the position of these hinged plates,adjustable the side .walls 28'of the box 18 are provided with a seriesof openings 30 in suitable graduated arrangement. The hinged plates26and' 27 are also provided with slots 31 for receiving screws 34 securedto extension, or'compalnion wings or plates 32 and 33respective'ly. The

screws 34 may be tightened wherever it is desired within the slotswhereby the total length of the diaphragins or partition walls formed bythe plates 25, the wings 26 and 27 and their extensions 32 and 33,respectively, may be increased or decreased as desired.

Numeric indications 35, marked on the outside of the load carrying box18, will facilitate the angular adjustment of the partition walls, thenumerals being arranged in a predetermined relation with the cubiccontents of the spaces confined by the walls 23 of the box and thepartition walls.

One of the compartments formed in this way may serve to receive sand;another compartment may receive rock or gravel, and a third compartmentmay receive the cement necessary for the making of concrete.

The material which is selectively dumped into these various compartmentsof the box by any desired mechanism will be discharged from thecollective space of the box through an opening adjacent the bottomcontrolled by a gate 36', this gate being hinged at its upper edge tothe curved front wall 19 of the box, as shown in Figures 3 and 4; thegate, however, being normally held in closed position by a latchcomprising hooks 106 rigidly mounted on a rock shaft 105.

Brackets 37, Fig. 2, rigidly secured to the rear wall 21 of the loadcarrying box 18 serve for rotatably supporting a shaft 38 from whichlateral arms 39 extend. The front ends of these arms aresecured to ashovel or scoop indicated at 43. The mechanism for actuat: ing thisshovel or scoop so as to move it to charging or discharging position,and the mechanism for opening and closing' the scoop, does not form thesubject matter of the present invention but is described in detail inPatent No. 1,506,762, dated September 2nd, 1924, and of whichapplication the present is a divisional.

In said Patent No. 1,506,762 the means are also described for adjustinga cam 50 secured to the side wall 23 of thebox 18 whereby the dischargemovement of the scoop 43 may be controlled so as to effect the dischargeinto one or the other of the several compartments of the box as may bedesired.

The sand, stone and cement having been deposited in the variouscompartments of the box and'having been collectedon the bottom wall 22thereof-may then be discharged in mixed conditionupon opening of thegate 36. This mechanism also is under the control of the operator seatedat 6. It comprises a transverse shaft or bar 100, Fig. 1, which isretatably mounted at the rear wall of the box, also preferably in thebracket 37. This transverse pin or shaft is rigidly connected with ahand lever 101 within reach of the operator. An arm 102 also secured tothe transverse pin orshaft 100 is movably connected by the link '103with an angular arm 104 Fig.4 mounted on the transverse shaft 105 whichis supported as described above in the frame of thetruck. From Fig. 3 itis apparent that a helical spring 107 surrounds a portion of the shaft105, one end of the'spring being secured to the shaft while the otherend of the spring is anchored in the bearing of the same. This springtherefore has a tendency also to rotate the latch hooks 106 in apredetermined direction, namely, in a direction in which they will holdthe lower edge of the gate 36 in closed position as shown in Figs. 3 and4.

Upon release of these hooks 106 etl ectedby the operator throughmanipulation of the hand lever 101 the gate will by its own weight swinginto open position and may bereturned to closed position when the scoop43 is low cred, as for instance by the mechanism described in Patent No;1,506,762. V r k For this purpose the gate as shown in Fig. 3 isprovided with lugs 108 of wedge shape. These lugs will be contacted bythe scoop in the return movement of the latter and force the gateinwardly towards the position shown in Fig. 4-. 'When the scoop hasreturned to its charging position, as indicated in Fig. 4, the gatewill'close and the latch hooks 106 automatically snap back owing to theaction of the spring 107, therebylocking v the gate.

The support of the load carrying box from the truck preferably includesa yielding support, as shown in Fig. 3, and comprises spring shackles110 which are connected to a rela tively heavy transverse spring 111011which a rear portion of the box 18 rests. Any other suitableconstruction, however,may be used in place of the constructionjustdescribed.

The operation of the device will be apparent from the above description.W hen it is desired to use the'box for conveylng a batch of material toa concrete mixer and to. proportion the ingredients of the batch in accordance with the requirements, the pivoted partitions 26 and 27 withinthe box are adjusted thru release of the holding bolts 29 and fixingthese boltsagain in the new selectively determined position. The truckis then advanced to the various heaps of the ingredicuts and afterdriving the scoop 43 into each heap the operations of raising it todischarge position and of again lowering it are repeated until thedesired quantity of each of the in gredients has been deposited in theselected compartment, the selection of the compartment being effectedthrough suitable adjustment of the cam at the side wall of the box.

This operation is carried out for each of the materials and compartmentsrespectively, and then'the truck with its loaded box is driven to thereceiving end of the shovel or shoe of a concrete mixer (not shown),while the scoop 43 is held in" raised position, indicated in dottedlines in Fig. 1. The attendant then operates the lever 101 to releasethe gate and the batch mixed in the collective chamber, which is belowthe individual compartments, is dumped into the shoe of the concretemixer. The emptied truck is then withdrawn and the operations may beginagain. i

It is obvious that it is not necessary to utilize the variouscompartments provided in the box for receiving dilierent classes ofmaterial but that this load carrying box may also be used for conveyingin all of the compartments the same material or mixture of materials sothat this load carrying box may be utilized in the SELHIQWfiy asthe'ordinary body of power controlled vehicles. It is obvious that themachine also can be used as a tractor for pulling other road equipment,mixers, concrete machines and the like, and that the capacity of theload carrying box may be increased to satisfy all practicalrequirements.

I claim:

1. A load carrying box for vehicles having partition walls, thepartition walls comprising portions fixed to the outer walls of the box,other portions movably attached to the fixed portions, and additionalportions adjustable with respect to the movable portions,

and movable together with the same.

2. A load carrying box for vehicles having partition walls, thepartition Walls each comprising a portion fixed between the lateralwalls of the box, a section hinged to the lower edge of the fixedportion and an extension section slidable with respect to the hingedsection, and means for retaining said slidable and said pivotal sectionin predetermined adjustment with respect to each other.

3. A load carrying box for vehicles having partition walls, eachpartition wall comprising a fixed section and a movable section, meansfor extending the movable section longitudinally and in a direction awayfrom the fixed section, and means for retaining the movable section inits adjusted extended condition.

In testimony whereof I affix my signature at 114 Grand Avenue,Milwaukee, Wisconsin.

GEORGE MANIERRE.
